GROW #14 Tangy

Few improvements from last week. I clearly see some growth but the plant seems a little behind, on the feeble side. Since yesterday the top leaves started to display veined light discolouration that makes me think 1. ph fluctuations: which is negligeble, 0.5 and still well below 7 2. nute burn: also not the case as the ppm is relatively low, around 450 to 550 3. light stress: I m using new leds so I am not entirely familiar with it yet. at present it is on 4.2 out of 10 of potency. Besides she is the sole displaying this in the tent. The light schedule was changed from 24/0 to 20/4 as I felt that I don't know my new led lights well enough to try this out as a first time. They are 6 times more powerful (allegedly) from my previous three small ones combined and I do look forward to seethe difference density and product once used at 100% capacity.
